Abstract: The evaluation of seismic monitoring station network is a complex system engineering. The research and establishment of evaluation index system is a very important technical link, also as an essential core element for the implementation of quantitative evaluation. In this paper, we have carried out the extensive research and analysis on the system evaluation model, and the principles and methods of the system evaluation index system construction firstly. At the same time, we have studied, analyzed and discussed the infrastructure and system characteristics of earthquake monitoring station network comprehensively, according to the current business system of earthquake monitoring, and also the history, current situation and future development of earthquake monitoring in China. On this basis, by analyzing and clarifying the evaluation objectives of the seismic monitoring station network, a three-level evaluation index system is studied and constructed, which includes the decomposition objectives of layout rationality, measurement accuracy, observation reliability, data scientificity, and so on. The comprehensive analysis shows that, the evaluation index system constructed in this paper thoroughly and objectively reflects the basic characteristics of seismic monitoring information system in our country, which is expected to provide neccessary reference and support for the comprehensive evaluation of seismic monitoring station network.

Key words: Earthquake monitoring station network, System characteristics, Evaluation model, Index system, Comprehensive evaluation
